Merger of the German subsidiaries into PSI Software SE

Berlin, June 26, 2024 - PSI Group is streamlining its organizational structure by merging its German subsidiaries into the Group's parent company, PSI Software SE. The structural simplification facilitates the PSI-wide harmonization and streamlining of business processes, unlocks synergy potential and improves the overall scalability of the business.

With this important step, PSI is creating the organizational preconditions for the Group's positioning as a modern, integrated software company. At the same time, this streamlining supports the focus on profitable growth and strengthens the Group-wide PSI identity.

For PSI customers, the relationship with the business units of PSI Software SE will not be affected by this step. They will benefit from an even stronger financial basis and an increased pool of integrated expert resources.
